For the second time in World of Warcraft's history, players have inadvertently spread a potent in-game virus across servers, leading to widespread player deaths and a temporary epidemic of what has been dubbed "Corrupted Blood 2.0." The Withering Contagion debuff, normally contained within the Brackenhide Hollow dungeon, escaped its confines due to a glitch, causing players who contracted it to emit an explosion of "goo."
The debuff began spreading to players outside of Brackenhide Hollow sometime before July 3, though the exact start date remains unclear. The NPC responsible for inflicting the Withering Contagion, Vile Rothexer, has been present in the game since the introduction of Patch 10.0.0 on October 25, 2022, making the outbreak's emergence surprising. However, the issue was short-lived, as a hotfix on July 3 patched the exploit.
Despite its brief duration, the plague managed to wreak havoc across the Moon Guard U.S. server. Videos shared on social media platform BlueSky by user meggoart documented the virus's spread through various in-game locations, including a notable scene at Lion Pride's Inn, depicting numerous player characters covered in "slime-covered corpses."
The "Corrupted Blood 2.0" incident draws a direct parallel to a similar event in 2005, famously known as the original Corrupted Blood plague. That contagion spread similarly when the boss Hakkar the Soulflayer infected players during a raid event. The 2005 incident became so notable it acquired its own Wikipedia page.
While the "Corrupted Blood 2.0" incident was likely a nuisance for some players, its rapid containment contrasts with the original outbreak, which reportedly lasted for weeks before Blizzard intervened. On the other hand, player accounts indicate the Withering Contagion debuff dealt "23,360 Nature damage" each time it triggered. This level of damage would have been devastating to lower-level characters, suggesting the quick patch was perhaps for the best.
